What if we could buy the books for one human, make the human read all the books, and somehow we would be able to clone this human in a way that they remember the book contents.
I think we should pay authors a fair wage based on some measure of the quality of the content instead of how well the book sells.
There's no reason for Harry Potter for example being 10000 times more valuable than a book on quantum mechanics only because the former is more popular and the latter is on a more obscure topic.
Ok, it doesn't tell much about AI and fair use, but I find it funny that your thought experiment is actually something you can do in real life.
